Re: [Haskell-beginners] Question on (x:xs) form

Why are the brackets required? And what do they signify?

Eg reverse' x:xs = reverse' xs ++ [x] results in a parse error.

I just want to add that "prefix application"/juxtaposition binds stronger than "infix application" and that therefore spaces should be put around infix symbols (like ":") to stress this fact: reverse x:xs is the same as reverse x : xs and both are parsed as (reverse x) : xs which is different from reverse (x : xs) although "x:xs" almost looks like "(x:xs)" Cheers Christian
